Daylight Saving Time 2027: Exact Dates and the States That Never Change Clocks
-- reading | Updated:
In 2027 you'll lose an hour of sleep in March and get it back in November — unless you live in one of the two states where clocks never move at all.

In 2027, Daylight Saving Time begins on Sunday, March 14 (clocks jump from 2:00 a.m. to 3:00 a.m. — you lose an hour of sleep) and ends on Sunday, November 7 (clocks fall back from 2:00 a.m. to 1:00 a.m. — you gain an hour). The rule is fixed by federal law: DST starts the second Sunday of March and ends the first Sunday of November.
Twice a year, "daylight saving" becomes one of the most-searched phrases in America. And twice a year, millions get the direction wrong — showing up an hour early to work in March or an hour late in November. Here's your cheat sheet for both 2027 changes, plus the states that sit them out entirely.
The Two 2027 Dates, At a Glance
| Event | Date | Clock change | Effect |
|---|---|---|---|
| Spring forward (DST starts) | Sun, March 14, 2027 | 2:00 am → 3:00 am | Lose 1 hour of sleep; more evening light |
| Fall back (DST ends) | Sun, November 7, 2027 | 2:00 am → 1:00 am | Gain 1 hour; darker evenings |
Which States Don't Change Clocks?
Two stay on standard time year-round: Hawaii and Arizona (with one twist — the Navajo Nation inside Arizona does follow DST). U.S. territories including Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa and the Northern Mariana Islands also skip the switch. Everyone else springs forward and falls back on schedule.
Is This the Year DST Ends?
Probably not. The Sunshine Protection Act — which would make daylight saving time permanent — has circulated in Congress for years but has not been enacted. Until it is, federal law keeps the clock changes exactly where they are, so plan around March 14 and November 7 with confidence.
The Health Detail Nobody Mentions
The spring shift costs you a full hour overnight, and studies have tied the days after it to a spike in car accidents and heart-related emergency calls as bodies adjust. The easy fixes: go to bed 15–20 minutes earlier for two or three nights before March 14, push morning coffee later that first day, and remember your microwave and car clock won't update themselves even if your phone does.
What It Means for You
Set two phone reminders now: Saturday night, March 13, 2027 ("move clocks forward") and Saturday night, November 6 ("move clocks back"). If you schedule calls with Europe, note their dates differ — the EU and UK switch on March 28 and October 31, 2027, creating two short windows when New York and London are temporarily 4 or 6 hours apart instead of 5.
